Undated (AP) It's going to be another busy day for democrats Barack Obama and Hillary Clinton, but the republican they're hoping to take on in the fall, John McCain, will be getting some holiday weekend downtime at his home in Arizona.

Obama wraps up three days of campaigning in Florida with an address at a Cuban Independence Day celebration in Miami. Clinton stumps in South Dakota.

New York governor David Paterson, one of the convention superdelegates backing Clinton, is hinting he may be changing his mind. Paterson says Clinton seems to be getting a little desperate. He's also calling on her to drop efforts to count votes from therenegade primaries in Florida and Michigan. Both states defied party rules by moving up their elections. And the New York governor says Clinton shouldn't “trample on the process.”

With only three more primaries to go, Obama leads Clinton by nearly 200 delegates, so even if she did get a favorable ruling on Florida and Michigan, she'd still be trailing.
